ABSTRACT:
A delay circuit including: a P-channel enhancement-type transistor (Q.sub.11), linked between an input terminal (IN) and an output terminal (OUT); a capacitor (C) connected to the gate of the transistor (Q.sub.11); a charging switch (SW.sub.1) for charging the capacitor (C); a discharging switch (SW.sub.2) for discharging the capacitor (C); and a control circuit (CONT) for controlling the charging switch (SW.sub.1) and the discharging switch (SW.sub.2). The delay time period is determined by the discharging operation of the discharging switch (SW.sub.1) after the charging operation of the charging switch (SW.sub.1).
